Let’s Talk Stem Cells Part 6: Stopping Growth on Contact

One of many fascinating features of our mesenchymal stem cells (MSCs) is that they are designed to stop growing on contact. In other words, when MSCs touch, they stop multiplying, or making copies. Embryonic stem cells and induced pluripotent stem cells (iPS) don’t do this. Why is this significant? Because it’s this inability to stop … Continued
